Winter Plumbing Preparation: Protect Your Pipes
Essential winter plumbing preparation tips to protect your pipes from freezing and bursting.
Read More →A sump pump can sit idle for months and then be needed in a storm. A short maintenance routine keeps it ready to run on demand.
A sump pump is one of the least visible but most valuable pieces of equipment in a home with a basement or crawlspace. It collects groundwater that seeps into a basin below the floor and pumps it away from the foundation before it can rise and flood the space.
Because the pump runs mostly during heavy rain or spring snowmelt, it can sit untouched for long stretches. Float switches stick, discharge lines clog, check valves corrode, and screens fill with silt. When the pump is finally needed, it may not start.
This guide explains how a sump system works, how to test and clean it, how to check the discharge path, and how to prepare before the wet season. A small amount of routine care goes a long way toward avoiding a flooded basement.

Understanding the parts makes troubleshooting much easier:
Water may arrive through a perimeter drain, a gravel layer under the floor, or a direct drain pipe. The system only works if each part is clear and functional, so the pump is not the only component worth checking.
Testing is the single most important maintenance step, and it takes only a few minutes. Aim to test monthly during wet months and at least once before the rainy or thaw season.
If the pump does not start, first check the power: the outlet, the breaker, and any GFCI protection. If power is present and the pump still will not run, the float switch or the pump itself may have failed. A pump that runs constantly usually points to a stuck float or too much incoming water.
Silt, gravel, and debris settle in the basin over time and can jam the float or clog the pump inlet. Clean the basin once a year, or more often if your water carries a lot of sediment.
Do not reach into a basin with a pump that is still plugged in. A jammed or partially submerged pump can start without warning, and the impeller can cause serious injury.
A clear, correctly installed discharge path is just as important as a working pump. Water that cannot leave the basin will simply overflow.
If the pump runs but little water exits, a clogged or frozen line is a common reason. Thaw or clear the line before assuming the pump has failed.
Storms that bring heavy rain often knock out power, which is when a sump pump is needed most. A backup system protects you when the primary pump loses electricity.
Plug the pump into a dedicated GFCI outlet and keep the cord out of the water path. A dedicated circuit reduces the chance that another appliance will trip the breaker during a storm.
Run through this list before the wettest part of your year:
Keeping roof gutters clear and extending downspouts several feet from the foundation reduces how much water reaches the sump basin in the first place. That reduces how hard the pump has to work when storms arrive, and it pairs well with the freeze protection steps in our winter plumbing guide.
Most sump pump failures fall into a few familiar categories:
If a pump has failed more than once or is making grinding noises, replacement is usually more reliable than repeated repairs. Most pumps last about seven to ten years with regular use.
Call a licensed plumber when you are unsure whether the pump, the switch, or the discharge line is at fault, or when you need a backup system installed. A professional can also evaluate whether the basin, pit, and drainage around the foundation are adequate for your water table.
If the pump is near the end of its expected life, replacing it before the wet season is a sensible step. A new pump with fresh seals and a clean basin is far less likely to fail during the storm that matters most.
